Description

Technical Field

[0001] This application relates to the field of vaginal dilator technology, and more particularly to an adjustable animal vaginal dilator with an air bladder and method. Background Technology

[0002] In veterinary clinical practice and animal experiments, intrauterine procedures (such as intrauterine sampling, drug administration, embryo transfer, or disease diagnosis) in small animals (such as cats and rabbits) often require exposure of the cervix. Currently, there are two main methods: 1. Open abdominal surgery to directly expose the uterus and cervix; this method is highly invasive, has a slow recovery time, and a high risk of infection. 2. Using a mechanical vaginal speculum (duckbill speculum) for vaginal dilation. Existing veterinary vaginal speculum are mostly designed for large animals (such as dogs, sheep, and cattle).

[0003] Patent application number ZL201120054052.9 discloses a canine vaginal speculum with a lighting device, mainly employing a duckbill-type mechanical dilation structure, suitable for large animals. Patent publication number CN211049610U discloses a disposable vaginal speculum pad for animal embryo transfer, used in conjunction with a traditional duckbill-type vaginal speculum. Both of these devices primarily rely on mechanical dilation of the vaginal wall.

[0004] Traditional duckbill-type dilators are large and rigid, and cannot flexibly adapt to physiological curvature, resulting in difficulty in insertion, uneven dilation, and difficulty in fully exposing the cervix.

[0005] The dilation method is more invasive: mechanical duckbill dilation causes uneven pressure on the vaginal wall, which can easily cause local damage; for narrow vaginas, forced dilation may lead to tearing or bleeding.

[0006] Poor cervical exposure: Existing instruments are difficult to specifically dilate the vaginal fornix, making it impossible to stably and fully expose the cervix in the operating field, often requiring laparotomy to complete intrauterine procedures.

[0007] Lack of adjustability: The instrument has a fixed shape and cannot be adjusted according to individual differences in different animals (such as vaginal length, curvature, and narrowness), resulting in a low success rate of operation.

[0008] Therefore, this application proposes an adjustable animal vaginal dilator with an air bladder and a method thereof. Summary of the Invention

[0009] The purpose of this application is to address the technical problems identified in the background section by providing an adjustable animal vaginal dilator with an air bladder and a method thereof.

[0010] The technical solution of this application is as follows: On the one hand, this application proposes an adjustable animal vaginal dilator with an air bladder, including an inlet tube and a support bladder fixedly sleeved on the outer wall of the insertion end of the inlet tube. The end side wall of the inlet tube is also connected to the dilator. The inside of the inlet tube is provided with a trachea a and a trachea b. The trachea a and trachea b are respectively connected to the support bladder and the dilator for inflation. A light bulb is provided at the end of the inlet tube. It also includes an insertion protective component, which is installed at the insertion end of the inlet tube for safety protection. The insertion protective component includes a protective membrane sleeve, which covers the outside of the expansion bladder and the support bladder. The protective membrane sleeve can be pulled and stored inside the inlet tube.

[0011] Preferably, the support bladder is annular, and an inflation head a is inserted into the inner wall of the support bladder and the side wall of the inlet tube. The output end of the inflation head a extends into the interior of the support bladder, and the input end of the inflation head a is connected to the trachea a.

[0012] Preferably, the expansion bladder is umbrella-shaped, and an inflation head b is inserted into the inner wall of the expansion bladder and the side wall of the inlet tube. The output end of the inflation head b is connected to the interior of the expansion bladder, and the input end of the inflation head b is connected to the trachea b.

[0013] Preferably, both the inlet ends of trachea a and trachea b are equipped with valves, and the inlet ends of trachea a and trachea b are supplied with air via a syringe or a small air pump.

[0014] Preferably, a metal wire is fixedly connected to the inner wall of the inlet tube. The metal wire is a malleable metal wire used for curvature adjustment.

[0015] Preferably, there are several bulbs arranged in a ring at the end of the inlet tube.

[0016] Preferably, the inlet tube is provided with wires a and b, through which the light bulb is powered.

[0017] Preferably, the insertion protective component further includes a storage tube, and the end of the inlet tube is provided with a through-hole, with the storage tube fixedly connected to the inner end of the through-hole; A connecting rope is fixedly connected to the inner wall of the protective film sleeve, and a traction rope extending to the outside of the other end of the inlet tube is provided inside the storage tube. The traction rope is fixedly connected to the connecting rope. The storage tube is fixedly connected to a limiting plate at the end away from the opening, and the limiting plate has a through hole through which the traction rope moves.

[0018] On the other hand, this application proposes an adjustable animal vaginal dilation method with an air sac, comprising the following steps: S1: When the dilatation sac and support sac are not inflated, insert the end of the dilatation sac into the animal's vagina. The protective film cover is placed on the outside of the dilatation sac and support sac to reduce discomfort during insertion. S2: After insertion, pull the traction rope to retract the protective film sleeve into the storage tube, and then manually shape the curvature of the inlet tube to fit the animal's pubis. S3: The support sac and the dilator sac are inflated sequentially through trachea a and trachea b; the support sac dilates the vagina and the dilator sac dilates the fornix to expose the cervix, and the lighting is turned on to perform intrauterine operations. S4: Depress, remove the device.

[0019] Compared with the prior art, this application has the following beneficial technical effects: This application incorporates a support sac and a dilation sac at the end of the inlet tube. When inserted into the animal's vagina, the dilation sac and support sac are in a deflated state, making them small and easy to insert into the vagina of small animals. Furthermore, the outer sides of the dilation sac and support sac are covered with insertion protective devices, which can reduce the animal's discomfort during insertion and also protect the bulb during vaginal insertion, preventing the bulb's outer surface from becoming blurred by mucus. Under the protection of the protective film, the subsequent bulb maintains clear illumination, providing sufficient local lighting and significantly improving the field of vision in the narrow vagina.

[0020] After insertion, the protective sheath can be stored in the storage tube, and then the dilator and support sacs can be inflated. The flexible expansion of the air sac avoids the local high pressure damage caused by rigid stretching, significantly reducing the risk of vaginal wall tearing and bleeding, and achieving non-invasive or minimally invasive operation.

[0021] This application, by setting a metal wire on the inner wall of the inlet tube, allows for manual adjustment of the curvature (fitting the pubic bone) according to individual animal differences. It is suitable for small animals such as cats and rabbits of different sizes and physiological curvatures, thereby improving the success rate of the operation.

[0022] In this application, a dual-stage balloon is used for step-by-step dilation. The first stage stabilizes the vaginal canal, while the second stage, an umbrella-shaped balloon, precisely dilates the fornix, fully enveloping the cervix and placing it in the central field of vision, thus avoiding the problem of insufficient exposure associated with traditional instruments.

[0023] In summary, this application is simple and safe to operate, easy to insert in the deflated state, has independent inflation control, and is easy to remove after operation; the overall structure is simple and low in cost, which facilitates its application in veterinary clinical practice and experiments, reduces the need for open surgery, and lowers the risk of animal stress and infection.

[0031] like Figures 1-6 As shown, this application discloses an adjustable animal vaginal dilator with an air bladder, comprising an inlet tube 3 and a support bladder 2 fixedly sleeved on the outer wall of the insertion end of the inlet tube 3. The end side wall of the inlet tube 3 is also connected to the dilator bladder 1. The inlet tube 3 is a slender tubular structure made of medical-grade plastic material, with a smooth exterior for easy insertion into the animal's vagina. A metal wire 8 is fixedly connected to the inner wall of the inlet tube 3. The metal wire 8 is a malleable metal wire used for curvature adjustment; the metal wire 8 is made of 304 stainless steel or shape memory alloy wire, allowing the operator to manually bend the inlet tube 3. The inlet tube 3 is internally equipped with trachea a4 and trachea b5, which are connected to the support bag 2 and the dilation bag 1, respectively, for inflation. Each trachea a4 and trachea b5 has a valve at its input end. Inflation is supplied to the input ends of trachea a4 and trachea b5 via a syringe or a small inflation pump. When inflating the dilation bag 1 or the support bag 2, the corresponding valve is opened; after inflation, the valve is closed; and when deflation occurs, the valve is reopened. A bulb 10 is installed at the end of the inlet tube 3. Several bulbs 10 are arranged in a ring at the end of the inlet tube 3 to increase the illumination range. An electric wire a6 and an electric wire b7 are internally installed in the inlet tube 3. Electric wires a6 and b7 are the neutral and live wires, respectively, supplying power to the bulbs 10. The light source of the bulb 10 is directed towards the cervix. Electric wires a6 and b7 can be connected to a small battery or an external power source.

[0032] Specifically, the support sac 2 is annular, and an inflation head a9 is inserted into the inner wall of the support sac 2 and the side wall of the inlet tube 3. The output end of the inflation head a9 extends into the interior of the support sac 2, and the input end of the inflation head a9 is connected to the trachea a4. After inflation, the support sac 2 expands uniformly in a ring shape to open the entire vaginal cavity, providing a stable operating channel and assisting in positioning. The dilation sac 1 is umbrella-shaped, and an inflation head b11 is inserted into the inner wall of the dilation sac 1 and the side wall of the inlet tube 3. The output end of the inflation head b11 is connected to the interior of the dilation sac 1, and the input end of the inflation head b11 is connected to the trachea b5. After inflation, the dilation sac 1 is umbrella-shaped and is specifically used to dilate the vaginal fornix, fully surrounding and exposing the cervix to the central view. The dilation sac 1 and the support sac 2 can be made of medical-grade silicone or TPU to ensure biocompatibility. A hydrophilic coating can be added to the surface of the balloon to reduce insertion resistance.

[0033] Furthermore, it also includes an insertion protective element 12, which is disposed at the insertion end of the inlet tube 3 for safety protection, reducing the animal's discomfort when inserted into the animal's vagina. The insertion protective element 12 includes a protective film sleeve 121, which covers the outside of the dilation sac 1 and the support sac 2. The protective film sleeve 121 can be pulled and stored inside the inlet tube 3. The protective film sleeve 121 is made of natural latex, is thin, and has a certain degree of elasticity. The insertion protective element 12 also includes a storage tube 124. The end of the inlet tube 3 has an opening 13, and the storage tube 124 is fixedly connected to the inner end of the opening 13. The storage tube 124 is used to store the protective film sleeve 121. A connecting rope 122 is fixedly connected to the inner wall of the protective film sleeve 121. A traction rope 123 extending to the outside of the other end of the inlet tube 3 is disposed inside the storage tube 124, and the traction rope 123 is fixedly connected to the connecting rope 122. By pulling the traction rope 123, which in turn pulls the connecting rope 122, the protective film sleeve 121 is retracted into the storage tube 124. A limiting piece 125 is fixedly connected to the end of the storage tube 124 away from the opening 13. The limiting piece 125 has a through hole 126, through which the traction rope 123 movably passes. By setting the limiting piece 125, the protective film sleeve 121 is confined within the storage tube 124 during retraction.

[0034] The working principle of this embodiment is as follows: the dilation sac 1 and the support sac 2 are inserted into the vagina of a small animal. When inserted into the animal's vagina, the dilation sac 1 and the support sac 2 are in a deflated state, making them small and easy to insert into the animal's vagina. Furthermore, the outer sides of the dilation sac 1 and the support sac 2 are covered with a protective film sleeve 121, which reduces discomfort for the animal during insertion and also protects the bulb 10 from being obscured by mucus on its outer surface. Under the protection of the protective film sleeve 121, the bulb 10 maintains clear illumination, providing sufficient local lighting and significantly improving the field of vision within the narrow vagina.

[0035] After insertion, the protective sheath 121 can be retracted into the storage tube 124. The specific operating steps are as follows: pull the traction rope 123 from one end of the introduction tube 3. The traction rope 123 drives the connecting rope 122 to move into the storage tube 124, thereby allowing the protective sheath 121 to be retracted into the storage tube 124 through the opening 13, exposing the dilator 1 and the support sac 2. One end of the trachea a4 and trachea b5 is connected to the syringe. By pushing the syringe piston, the dilator 1 and the support sac 2 are inflated, fully surrounding the cervix and placing it in the central field of vision. The light bulb 10 is then turned on to perform intrauterine manipulation. This application uses flexible balloon dilation, avoiding the local high-pressure damage caused by rigid stretching, significantly reducing the risk of vaginal wall tearing and bleeding. By setting a metal wire 8 on the inner wall of the introduction tube 3, the curvature (fitting the pubic bone) can be manually adjusted according to individual animal differences, making it suitable for small animals such as cats and rabbits of different sizes and physiological curvatures.

[0036] After the uterine cavity operation is completed, open the valves at the input ends of trachea a4 and trachea b5, pull the syringe piston in the opposite direction to extract the gas from the support sac 2 and the dilation sac 1, thereby deflating the dilation sac 1 and the support sac 2, making it easier to remove the device.

[0037] This application proposes an adjustable animal vaginal dilation method with an air sac, comprising the following steps: S1: When the expansion sac 1 and the support sac 2 are not inflated, insert the end of the expansion sac 1 into the animal's vagina. When inserted, the protective film sleeve 121 covers the outside of the expansion sac 1 and the support sac 2, which can reduce discomfort and also shield and protect the bulb 10. S2: After insertion, pull the traction rope 123 to put the protective film sleeve 121 into the storage tube 124, and then manually shape the curvature of the inlet tube 3 to fit the animal's pubic bone; S3: Inflate the support sac 2 and the dilation sac 1 sequentially through trachea a4 and trachea b5; the support sac 2 dilates the vagina and the dilation sac 1 dilates the fornix to expose the cervix, and the lighting is turned on to perform intrauterine operations. S4: Extract the gas from the support bladder 2 and the expansion bladder 1, thereby deflating the expansion bladder 1 and the support bladder 2, and remove the device.

Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
